The problem of stationary electrolysis of a solution of nonamphotheric comp
ounds (acids or bases) is considered. The analysis is performed by taking i
nto account the mobility dependence on pH. The properties of such a system
are also compared with the ones pertaining to the solution of an amphoteric
substance. It is anticipated that steady-state electrolysis of free acids
and bases, in a convection-free system, might be useful for creating narrow
pH gradients in rather acidic and alkaline milieus, which might be adopted
for focusing without resorting to conventional carrier ampholytes or immob
ilized pH gradients.
